Technical Information 1: General Notes On Cable Sizing

General notes on cables.

All cables are made up of a number of strands. Generally these strands are 0.20mm or 0.30mm diameter. In our list for each cable we also give the cross sectional area in sq mm and the continuous current carrying capacity in amps.

The breakdown of the cable specification 28/0.30mm, 2mm2, 17.5amp is as follows:

The following equation may prove useful to work out a cable size required amps = watts/volts.

Coloured cables. When two colours are given, the first colour is the main colour, the second colour is the 'tracer' (usually two thin traces of colour which run straight down the cable). eg. Black/white has black as the main colour and white as the tracer colour.
